Question : 57 of 65

Marks: +1, -0

A rigid rod of length

1 {m}

is resting at an angle

θ=45^{∘}

as shown in the figure. The end

{P}

is dragged with a velocity of

U=5 {m} {/} {s}

to the right. At the instant shown, the magnitude of the velocity V( in m/s) of point

{Q}

as it moves along the wall without losing contact is

Solution:

\;{V_{P}}/{I_{P Q} P}=\;{V_{Q}}/{I_{P Q} Q}

Hence,

{V}_{ {p}}= {V}_{ {Q}}=5 {m} {/} {sec}
